I crocheted this small hexagon using left over white thread from a previous project though I imagine this pattern would look fantastic worked up with vibrant color yarn. The materials I used are a size 3 crochet thread with a size 0 crochet hook. While I have not tested this pattern using any other type of yarn I am pretty certain it can be worked up in a worsted weight yarn as well. My example measures approximately 3.5 inches
